For group-living mammals, social coordination increases success in everything from hunting and foraging (Crofoot and Wrangham in Mind the Gap, Springer, Berlin, 2010; Bailey et al. in Behav Ecol Sociobiol 67:1–17, 2013) to agonism (Mosser and Packer in Anim Behav 78:359–370, 2009; Wilson et al. in Anim Behav 83:277–291, 2012; Cassidy et al. in Behav Ecol 26:1352–1360, 2015). Cooperation is found in many species and, due to its low costs, likely is a determining factor in the evolution of living… 
Sexually dimorphic aggression indicates male gray wolves specialize in pack defense against conspecific groups
Aggression directed at conspecific groups is common among gregarious, territorial species, and for some species such as gray wolves (Canis lupus) intraspecific strife is the leading cause of natural
The effect of domestication on post-conflict management: wolves reconcile while dogs avoid each other
TLDR
Evidence is provided for reconciliation in captive wolves, which are highly dependent on cooperation between pack members, while domestic dogs, which rely on conspecific cooperation less than wolves, avoided interacting with their partners after conflicts.
Wolves in space: locations of individuals and their effect on pup survival in groups of a cooperatively breeding canid
TLDR
This is the first study to provide indirect evidence for kin-directed attendance behaviour in wolves and it contributes novel methodology for investigating space use and helping behaviour in cooperative breeders at reproductive sites.
Back to the Future: A Glance Over Wolf Social Behavior to Understand Dog–Human Relationship
TLDR
Some behaviors of the dog’s ancestors that provide the basis for the expression of a cooperative society are selected, such as dominance relationships, leverage power, post-aggressive strategies, and playful dynamics between pack members.
In wolves, play behaviour reflects the partners' affiliative and dominance relationship
TLDR
The results support the social assessment hypothesis suggesting that social relationships outside of play are reflected during playful interactions, and revealed how different types of play, that is, playing in a competitive or relaxed way, may be related to different social relationships.
Post-conflict opponent affiliation reduces victim re-aggression in a family group of captive arctic wolves (Canis lupus arctos)
TLDR
The hypothesis that post-conflict opponent affiliation (POA) in wolves may have been selected for as a mechanism to avoid conflict escalation, which could lead to social disruption and hence jeopardize cooperative activities is supported.
Lethal Coalitionary Aggression Associated with a Community Fission in Chimpanzees (Pan troglodytes) at Ngogo, Kibale National Park, Uganda
TLDR
Two subsequent lethal coalitionary attacks by chimpanzees of the new western community on males of the now separate central community, one in 2018 and the second in 2019 are described, which highlighted the limits on protection afforded by long-term familiarity and the constraints on costly cooperation among male chimpanzees.
No evidence for a relationship between breed cooperativeness and inequity aversion in dogs
TLDR
The results do not provide support for the hypothesis that inequity aversion and cooperation co-evolved, but they illuminate potential differences in selection pressures experienced by cooperative worker and independent worker dog breeds throughout their evolutionary history.
Identification of potential signature whistles from free-ranging common dolphins (Delphinus delphis) in South Africa
TLDR
It is suggested that individual identity information may be encoded in these whistle contours, because the large group sizes and high degree of vocal activity characteristic of this dolphin species generate a cluttered acoustic environment with high potential for masking from conspecific vocalisations.

Group composition effects on aggressive interpack interactions of gray wolves in Yellowstone National Park
TLDR
Observations of aggressive interactions between wolf (Canis lupus) packs over an extended period are used and pack characteristics are used to determine which groups had an advantage over their opponents, highlighting that some individuals are more valuable than others during interpack conflicts.
Communal hunting and pack size in African wild dogs, Lycaon pictus
TLDR
In the Selous Game Reserve, Tanzania, wild dog pack size ranged from three to 20 adults (3–44 including yearlings and pups), data showed that hunting success, prey mass and the probability of multiple kills increased with number of adults.
Wolves : behavior, ecology, and conservation
Wolves are some of the world's most charismatic and controversial animals, capturing the imaginations of their friends and foes alike. Highly intelligent and adaptable, they hunt and play together in
EVOLUTION OF HELPING BEHAVIOR IN COOPERATIVELY BREEDING BIRDS
TLDR
It is argued that there is no obvious dichotomy between cooperative societies based on natal philopatry and the formation of extended families, and those formed via recruitment of unrelated individuals into coalitions.
Chimpanzees share food for many reasons: the role of kinship, reciprocity, social bonds and harassment on food transfers
TLDR
The analyses suggest that food transfers serve multiple functions for chimpanzees, and individuals may use food transfers to enhance the welfare of closely related group members, strengthen social relationships with favoured partners and reduce the costs of persistent solicitations.
Density-dependent intraspecific aggression regulates survival in northern Yellowstone wolves (Canis lupus).
TLDR
Assessment of the effect of wolf density, prey abundance and population structure, as well as winter severity, on age-specific survival in Yellowstone National Park indicates that density-dependent intraspecific aggression is a major driver of adult wolf survival in northern Yellowstone, suggesting intrinsic density- dependent mechanisms have the potential to regulate wolf populations at high ungulate densities.
Infanticide in Wolves: Seasonality of Mortalities and Attacks at Dens Support Evolution of Territoriality
Evidence for territoriality is usually correlative or post hoc as we observe the results of past selection that are challenging to detect. Wolves (Canis lupus) are considered territorial because of
Kin recognition and inbreeding avoidance in wild birds: the first evidence for individual kin-related odour recognition
TLDR
It is shown that European storm petrels, Hydrobates pelagicus, are able to distinguish kin from nonkin odours, and this results suggest that sophisticated olfactory communication is relevant in birds, and leads to important behavioural traits such as philopatry.
Social Relationships in a Group of Captive Wolves
TLDR
The social organization of a group of wolves in a large outdoor enclosure was followed through several breeding seasons and changes in social order and an increase in actual mating combinations suggest that some form of group selection could be operative in the wild.
Effects of kinship on territorial conflicts among groups of lions, Panthera leo
TLDR
Responses were unaffected by relatedness, and it remains possible that other aspects of behaviour during natural encounters among prides are affected by kin selection, as well as inclusive fitness theory.
